LU'IOHOBILE EXHAUST GENERATOR PROPULSION.

Application filed March 20, 1824 Serial No. 706,738.

To all whom it may concern:

Be it known that I, REUBEN STEINBERG,

a citizen of the United States, residing at -New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Automobile Exhaust Generator Propulsion, of which thefollowing is a specification.

The main object of this invention is to provide a gas propulsion meanswhich .uses the exhaust gases of a combustion engine to drive a fan orthe like which may be coupled to a generator or other mechanism.

-Another object is to provide an exhaust gas propulsion fan and anadditional auxiliary wind driven fan which are mounted on a generatordrive shaft and are coupled so that the gas propelled fan may be rotatedindependently of the air propelledfan, a novel clutch means beingprovided between both fans to accomplish the purpose.

Another object is to provide a means of diluting the exhaust fumes of a.combustion engine by the exhaust itself and aidedby' the air currentscaused by the motion of the engine.

These and other objects will become apparent in the description below,in which characters of reference refer to like-named parts in thedrawing.

Referring briefly to the drawing, Figure 1 is a side elevational view,showing the generator propulsion unit as applied in combination with acombustion engine.

Figure 2 is a top plan view of the same.

Figure 3 is a. sectional view taken longitudinally and centrally thruthe generator shaft propelling unit.

Figure 4 is a front elevational view of Figure 3.

Figure 5 is a cross sectional view taken on line 5-5 of Figure 3.

Figure 6 is a fragmentary elevational view of the clutch mechanismmounted between the fan units.

Referring in detail to the drawing, the numeral 10 indicates acombustion engine having four cylinders. From each cylinder, an exhaustoutlet 11 leads which communi cates 'with a manifold 12, said manifoldordinarily passing rearward to enter into a pelled by my device whichconsists essen- An automobile is usually provided with a generator 14 ora similar unit tially of a small semi-circular casing 15 and alarger;cas1ng 16, both casings being ]0lIled. by a flanged sleeve 17 andare mounted about a common axis. Theshaft 18 of the generator passesentirely thru the casing and partly thru the casing 16, the latterhaving a funnel face 19 at its outer end in which a large opening 20 isprovided.- An inlet opening 21 is provided 06 in the casing 15 at oneside, this opening communicating with the manifold 12 before it entersthe mufiler 13, and an opening 22, prov ded opposite to the opening 21,communicates with the muflier thru a pipe 23. Within the casing 15 andmounted on the shaft 18, a hub 24 is rigidly secured to said shaft andhas a plurality of radially extending arms 25 thereon to whichlongitudinally curved fan blades 26 are riveted, the width of said fanblades extending in a parallel direction with the axis of rotation. Inthe casing 16, an additional hub 27 is rotatably mounted on the shaft 18between collars 28, the latter bemg fixed to the shaft 18 by pins orother similar means. Fan blades 29 extend radially from the hub 27 ,thewidth of said blades being angular with respect to the axis of rotation.An outlet 30 is provided in the casing 16 and has a tube 31communicating therewith which extends rearward and enters into a tube 32which extends from the rear end of the mufller 13. Between the hubs 24and 27 of the fan members, an ad ditional collar 33 is mounted which hasa. flange 34 formed thereon. This flange is provided with a plurality ofteeth 35 at diametrically opposite positions on the face, said teethbeing engageable with a resilient tongue 36, the latter being mounted onthe adjacent face of a flange 37 which extends from one end of member27.

The device in being used, rotates the generator 14 which is used forproviding 618C"- trical energy. This is accomplished by passingexhaustgases from the cylinders of the combustion engine thru the manifold andinto the casing 15 thru the inlet 21. These gases strike the curved fanblades 26 in said casing and rotate the generator shaft 18 as the hub 24of the fan unit is rigidly secured to said shaft. The exhaust gases thenpass out of the casing 15 thru the outlet 22 and into'the muffler 13thru the pipe 23 to be emitted finally thru the tube 32. The auxiliaryfan mounted in the casing 16, is used as an aid to reduce the power loadof the fan member in the casing 15. air currents enter the 0pening'20 ofthe casin 16, the fan blades'29 andhub 27 are rotate When no air entersthe opening 20, these fan bladesand hub 27 may remain stationary, assaid hub is not rigidly mounted on the generator shaft. 18, but when'air does enter,-th'e resilient tongue 36 engages a tooth 35 mounted onthe flange 345m in this manner, aids in rotating the shaft 18. v Icla1m:-'-
